+# GrapheneOS AttestationServer Docker
+
+Dockerized deployment of [GrapheneOS AttestationServer](https://github.com/GrapheneOS/AttestationServer) for local attestation.
+
+## Overview
+
+This project provides a containerized setup for running your own GrapheneOS AttestationServer. It includes:
+
+- **AttestationServer** - The main Java application handling attestations
+- **Caddy** - Reverse proxy with HTTPS support
+- **SQLite** - Local database storage for attestation data
+
+## Prerequisites
+
+Before running the server, ensure you have:
+
+1. **Docker** and **Docker Compose** installed
+2. **TLS certificates** for `attestation.app` domain in the `certs/` directory:
+   - `certs/attestation.app.crt` - Certificate file
+   - `certs/attestation.app.key` - Private key file
+3. **DNS or hosts file configuration** to resolve `attestation.app` to your server
+
+## Pre-Launch Setup
+
+### 1. Prepare TLS Certificates
+
+Place your TLS certificates for `attestation.app` in the `certs/` directory:
+- `certs/attestation.app.crt` - Certificate
+- `certs/attestation.app.key` - Private key
+
+> **Note:** Certificate generation is up to you. You can use self-signed certificates for local testing or certificates from a trusted CA.
+
+### 2. Configure DNS or Hosts File
+
+The GrapheneOS Auditor app expects to connect to `attestation.app`. You must redirect this domain to your local server's IP address.
+
+#### Option A: Local Machine (hosts file)
+
+Edit your hosts file:
+
+**Linux/macOS:**
+```bash
+sudo nano /etc/hosts
+```
+
+**Windows:**
+```
+C:\Windows\System32\drivers\etc\hosts
+```
+
+Add the following line (replace `192.168.1.100` with your server's IP):
+```
+192.168.1.100 attestation.app
+```
+
+#### Option B: Network-wide (DNS)
+
+Configure your router or local DNS server (like Pi-hole or AdGuard) to resolve `attestation.app` to your server's IP address.
+
+#### Option C: Android Device (root required)
+
+If your Android device is rooted, edit `/system/etc/hosts`:
+```bash
+su
+mount -o remount,rw /system
+echo "192.168.1.100 attestation.app" >> /system/etc/hosts
+mount -o remount,ro /system
+```
+
+**Important:** You must configure this on the Android device running the Auditor app, not just the server.
+
+### 3. Create Data Directory
+
+Ensure the data directory exists for persistent SQLite storage:
+
+```bash
+mkdir -p data
+```
+
+## Running the Server
+
+### Build and Start
+
+```bash
+docker-compose up -d --build
+```
+
+This will:
+1. Build the AttestationServer from source
+2. Start the attestation service on port 8080 (internal)
+3. Start Caddy reverse proxy on ports 80 and 443
+
+### Check Status
+
+```bash
+docker-compose ps
+docker-compose logs -f
+```
+
+### Stop the Server
+
+```bash
+docker-compose down
+```
+
+### Stop and Remove All Data
+
+```bash
+docker-compose down -v
+rm -rf data/*.db data/*.db-*
+```
+
+## Usage
+
+1. Ensure your Android device has `attestation.app` pointing to your server IP
+2. Install [GrapheneOS Auditor](https://github.com/GrapheneOS/Auditor) app on your Android device
+3. Open the Auditor app
+4. The app will connect to your local attestation server instead of the official one
+
+
+## Directory Structure
+
+```
+.
+├── certs/                  # TLS certificates
+│   ├── attestation.app.crt
+│   └── attestation.app.key
+├── data/                   # SQLite databases (persistent)
+│   ├── attestation.db
+│   └── samples.db
+├── Caddyfile               # Caddy reverse proxy config

+├── docker-compose.yml      # Service orchestration
+├── entrypoint.sh           # Container entrypoint
+└── process-static-docker.sh # Static file processor
+```
+
+
+## Security Considerations
+
+- Keep your private key (`certs/attestation.app.key`) secure and never commit it to version control
+- The `.gitignore` file excludes sensitive files like certificates and databases
+- This setup is intended for **local/private use only**
+- For production deployment, use properly signed certificates from a trusted CA
+
+## License
+
+This Docker setup follows the same license as the upstream [GrapheneOS AttestationServer](https://github.com/GrapheneOS/AttestationServer).
